This way we can compare the already canonicalized principals,
while still passing the client specified target principal down
to the backend specific constrained_delegation() hook.

With S4U2Proxy tgt->crealm might be different from tgt_name->realm.

TODO: we need to add a S4U_DELEGATION_INFO to the PAC later.

Depending on S4U2Proxy the principal name for the resulting
ticket is not the principal of the client ticket.

For a normal TGS-REQ they're both signed with krbtgt key.
But for S4U2Proxy requests which ask for contrained delegation,
the keys differ.

This fixes Win2003 domain logons against Samba4, which need a
canonicalised reply, and helpfully do set that flag.
Specifically, they need that realm in krbtgt/realm@realm that these
both match exactly in the reply.

We need to use the name that the HDB entry returned, otherwise we
will not canonicalise the reply as requested.

By checking the client principal here, we compare the realm based on
the normalised realm, but do so early enough to validate the PAC (and
regenerate it if required).

Samba4 may modify the case of the realm in a returned entry, but will no longer modify the case of the prinicipal components.
The easy way to keep this test passing is to consider also what we
need to do to get the krbtgt account for the PAC signing - and to use
krbtgt/<this>/@REALM component to fetch the real krbtgt, and to use
that resutl for realm comparion.

This means that no reply packet should be generated, but that instead
the user of the libkdc API should forward the packet to a real KDC,
that has a full database.

I based this on Matthieu's import of lorikeet-heimdal, and then
updated it to this commit.

Some hdb modules (samba4) may change the case of the realm in
a returned result. Use that to determine if it matches the krbtgt
realm also returned from the DB (the DB will return it in the 'right' case)

This should allow master key rollover.
(but the real reason is to allow multiple krbtgt accounts, as used by
Active Directory to implement RODC support)

If we don't do this, the PAC is given for the machine accout, not the
account being impersonated.

This allows us to resolve multiple forms of a name, allowing for
example machine$@REALM to get an S4U2Self ticket for
host/machine@REALM.

This also adds a new hdb-glue.c file, to cope with Heimdal's
uncondtional enabling of SQLITE.
(Very reasonable, but not required for Samba4's use).

This extends the PKINIT code in Heimdal to ask the HDB layer if the
User Principal Name name in the certificate is an alias (perhaps just
by case change) of the name given in the AS-REQ. (This was a TODO in
the Heimdal KDC)
The testsuite is extended to test this behaviour, and the other PKINIT
certficate (using the standard method to specify a principal name in a
certificate) is updated to use a Administrator (not administrator).
(This fixes the kinit test).

This includes in particular changes to the KDC to resolve bug 6272,
originally by Matthieu Patou <mat+Informatique.Samba@matws.net>. We
need to sort the AuthorizationData elements to put the PAC first, or
else WinXP breaks when browsed from Win2k8.

The previous code only allowed an KRB5_NT_ENTERPRISE name (an e-mail
list user principal name) in an AS-REQ. Evidence from the wild
(Win2k8 reportadely) indicates that this is instead valid for all
types of requests.
While this is now handled in heimdal/kdc/misc.c, a flag is now defined
in Heimdal's hdb so that we can take over this handling in future (once we start
using a system Heimdal, and if we find out there is more to be done
here).

This requires a rework on Heimdal's windc plugin layer, as we want
full control over what tickets Heimdal will issue. (In particular, in
case our requirements become more complex in future).
The original problem was that Heimdal's check would permit the ticket,
but Samba would then deny it, not knowing it was for kadmin/changepw
Also (in hdb-samba4) be a bit more careful on what entries we will
make the 'change_pw' service mark that this depends on.

These changes add a krb5_data parameter named e_data to the windc_plugin to
allow the samba KDC to return extended error information in addition to the
standard KRB5KDC_ERR_* codes. Windows uses the extended information to provide
detailed information in user dialogs (e.g. account disabled, logon hours
restriction, must change password, etc.).
This particular commit modifies only heimdal code. Hopefully this can be
submitted and accepted into the upstream heimdal codebase.
